NAIL-DRIVING MACHINE FORBOO'IS AND sr'rons.

. Patented Nov. 3, 1914.

Boots and Shoes, of which the following description, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts. I I I This invention relates to nailing machines.

Although capable of general use, the invention is particularly intended for the use of repair shops and small establishments where custom work is doneorf where boots and shoes are made in a limited way. I

To the above end, the invention includes among its important features of novelty,

tlieprovision of a hopperor nail holder having means for holding a plurality of diflerent kinds or sizes of nails, and cooperating mechanism for selecting, at the will of the operator, anyone of said kinds or sizes; work-feeding mechanism; gaging means for regulating the distance apart of the nails; means for regulating the driving distance in from the edge of the work;

80 gaging means for regulating the driving of the nails across the butt of the sole; nail.- feeding mechanism; special nail-selecting mechanism; means for regulating the depth.

of driving, etc.

The constructional details of my invention will appear more at length from the following description read in connection with the accompanyingdrawings in which I have shown a preferred embodiment of my invention. I I

In custom shops and repair shops (and, forithjat matter, in regular shoe factories), it is often desirable to have'the opportunity of selecting from a variety of tacks or nails, but the usual nail driving machine'is provided simply with one hopper or receptacle. which carries a single kind or variety of tacks and nails to which the operator is. limited. .Acco'rdinglyqthe various features my 'machine center around thenovel idea of having a plurality of independent pockets or receptacles for a corresponding variety of nails. The arrangement is such that the nails maintain themselves at all times in. readiness for feeding forward in position to be driven, whenever the nozzle is turned to,

' of my;inventionv contained and embodied in such a position as to drive a particulartack, I

the selector being brought into play v at the same moment for selecting the given tack desired. -:The size of the hopper and the number of divisions or pockets therein will correspond to the requirements of any given place or use. 1 Asherein shown, I have provided a hopperl havingthree pockets 2, 3 and l-"inclined as clearly shownin Figs 1, 2, 7 and "9,each pocket'having converging sides and a groove or slot 5 in its bottom to direct thenails 6 down tothe nozzle 7 of the machine. Above the slot or nail passage I provide a vertical plate 8 normally having its bottom edge converging. slightly toward the lower end of the nail-way or passage 5 "and adjustable by means of a screw 9 bearing against an inclined edge 10,,and operating toprevent thenails from jarring out of the slot or passage 5, This plate 8 also prevents thenails from feeding down to thenozzletoo rapidly and serves in general to keep the nails in place and restrict them to their proper movement and operation. Above the hopper i is a hammer or actuator ll for operating a nail driver 12, said nail driver having a plate I or Washer 13 resting on top of the actuator 11, which:

is provided withaslot ii for the fr e move-[ ment therein of the driver 12 which recipro-.u

cates in the head 15 formed on the forward end of the hopper 1. The actuator 11 is in the form of a lever pivoted on an axle or bearing 16 mounted inseparated ears 17, Fig. l, extending from the upper side of the hopper or head of the machine which is secured sleeves or collars 18 IEOI'IIIBdJlH tegrally with the hopper or headof the 6 machine and parts 19 to the upper ends of gaged at its lower end by the grooved upper surface 29 of the inner end'of a treadle 30. The rods 20, 21' and 28 are slidingly mounted in the block like end 81 of a heavy arm 82 which carries a work-support in the form of a horn The latter has a limited downward yielding movement by reason of a'spring' 84' contained in a cavity formed therefor in the work-support, see Fig. 1, said spring engaging the work-support at its upper. end and a stud at its lower end, about which the work-support is free to swing, being retained by a pin 36 passing through a reduced portion 37 of said'stud. The block-like end 31 of the arm 32 serves also to retain together the supporting rods 20, 21, and the lifting rod 28 in mutually -su ortinv relation bein itself norm-all ED 7 b.

held yieldingly upward against a stop '88 a spring 39 on the rod 28 against the pressure of springs 40 on the rods 20, 21, (to operate as presently described) In a recess formed in thehub or block 23, see Figs. 8 and 4i, 1 mount two sliding lifting blocks or lugs 41 held outward by a spring 12. Each lug has at its outer end an inclined surface 43 and anoverhanging part 45* 414: the latter being in position to engage a shoulder 45 on the rear underside of the adjacent arm or part of the actuating lever 11, and the inclined surface 43 being in position to engage the inclined face d6 of a stationary cam 17 projecting inwardly from the adjacent stationary ear 17. Thus when the treadle is depressed the rod 28 and toggle link 26 operate to swing the 9.1 11124 forward on its pivot 16, thereby lifting the actuator lever 11 by the engagement with its shoulders 45 of the ends 44. of the lugs 41, and as the said actuator lever 11 is raised by thesaid forward swinging movement of the arm 24, the lugs l1 are moved backwardly as their inclined faces 43 slide along the cam surfaces 46, until the projectionst l escape from the shoulders 45, whereupon the'actuato'r lever or hammer 11 is instantly and powerfullyswung downward by a powerful spring 4:8 adjustab'ly' secured by a set bolt 4:9 to astationary part at one end and resting on a cross bar 51 of the lever or hammer 11 at its other end. As soon as the treadle is released, the spring 39. swings the arm 24L downwardly whereupon its lugs tl are automatically pressed by the spring 42 to their outward position ready again to lift the lever or hammer 11. As the hammer went up, it lifted the driver 12 by engagement with the plate 13 thereof, and as it went down, it correspondingly forced said driver downwardly by engagement with a collar 52 adjustably clamped at 53 on said driver 12.

nails are driven into the shoe. A blocr 54 of fiber or leather is preferably interposed above the head 15 for partially relieving the latter of the driving shock in the absence of a nail.

The nozzle 7 is removably mounted within the head 15, and is also free to turn or rotate on the driver, being automatically locked in desired position by a bolt 55 normally held forward by a spring 56 which is provided with a projecting thumb piece 57 at its upper end to enable the operator readily to release the bolt from engagement with the nozzle so that the latter may be re moved if desired. The nozzle is provided with a groove 58 to cooperate with the pointed end of the bolt 55 to prevent the nozzle being accidentally released, and in said groove are depressions 59 properly located and spaced apart to lock the nozzle in alinement with any given nail passage of the hopper when turned to that position. For this purpose theno'zzle is provided with a handle 60, see Fig. 9, by which it may be turned. The nails or tacks in each pocket of the hopper are normally held back or controlled by a light spring 61 carried by an upwardly projecting pin 62: so as to bear slightly but with sufficient force against the adjacent column of nails to prevent their falling or sliding down of their own accord. The nozzleisprovided at its rear side with a vertical slot leading to the nail passage 6'4 thereof and in this slot is mounted or reciprocated, a selector or pivoted pick-off 65 pivoted on a stud 66 carried by the upwardly extending arm or plate 67 of a foot or work-rest 68 arranged to slide vertically in a groove 6 in the nozzle against the resistance of spring 70, said stud 66 and a similar stud T1 traveling in slots 72 for keeping the parts steady. The adjacent portion of the nozzle is cut away up to a point 7 3 so as to permit the projecting overhanging shoulder 74 of said work-rest to move up to that extent, and the pick-oif or selector 65 is provided with a shoulder 75 to engage a pin 7 6 which operates at the,

right moment to swing the pick-0E on its pivot66 and thereby carry a nail into driv-- Theadjustment of the collar 52 serves to regulate the depth to which the ing' position. The pick-oif has a reduced point 77 for entering the tracker nail passage 5 and is provided with an inclined upper edge 7 8 down which the selected nailmay slide, so that as the pick off 65 rises, its point enters behind the foremost nail and deflects said nail down the surface78 just as the pick-off is forcibly swung forward by the engagement of its shoulder 75with, the pin Y6. The'part 68 of the work-rest carries a feed-wheel '79 provided with sharp teeth 'to'engage. the edge of the work andfeed it along at the proper moment. This wheel is looselymounted, on the hub 80 of apost 81 provided at lts upper end with a crank, or offset arm 82 having a roll 83 in. positlon to travelup anoblique surface or Way 8401? a block 85 adjustably supported by a thumb screw 86 in a' slot 87 of a gage arm 88. ex

tending out laterally from the nozzle. The

arm 88 is preferably vertically, adjustable by a screw 89on a projection 90 extending laterally from the nozzle. The beveled surface 84,ofthe block 85 slopes or inclines at a steeper angle at its forwardedge than at its rear edge,.the latter being. indicated in 8 at 91, so as to givea varying throw A. scale 92 '1nthe inclined surface 84, this rotation carrying the pawl forward 111a direction opposite to the arrow, Fig. 10, and then as the workrest is lowered, the spring 98 and engagement of the pawl 94 with the teeth 93 of the feed-wheel 79 cause the feed-wheel positively to turn in the direction of the arrow and feed the work. The distance of this feedingmovement, and hence of the spacing apart ofthe. nails driven into the shoe,is regulated by the adjustment of the block 8? along the scale 92. provided on an arm 100 projecting on the rear side of the work-rest to indicate to the operator the distance from the edge of the sole at which the nails will be driven. The arm 100 is slotted at 101 so that, upon loosening a thumb nut 102 which passes through said slot into the post 81, said post and the feed-wheel may he slid along said slot 101 andthereby turned up out of the way whenever it is desiredto nail across the butt of a sole. The rest 68 then bears on the shank and end of the butt so as to gage the distance in that the nails are driven, being spaced by the eye relatively to the gage marks103. i r

thumb nut 110.

wheel 7 9 is clamped thereon.

A scale 99 is In Figs. 11 and 12,1 have showna slightly. different construction of edge gage and feed: wheel, the edge-rest consisting of a wheel provided with a series of concentric space indications104, 105, 106, etc., alike for each series, but the series difi'ering from each other and. the cooperating pointer or indicator 107 slotted at 108so as to be radially adjusted to indicate for any one of said series desired and clampedbetween a post 109 extending upwardly from. the wheel and a v An opposite thumb nut 111 servesto clamp this mechanismin posit-ionon the part 100 the same as: the feed In use,.the operator places ,a shoeo ver the horn or work-support 33, He then depresses the treadle which: raises the rod; 28 and thereby lifts the horn 33 and shoe against. I

the work-rest 68, the operator atthe same time moving the shoe-against the edge gage or feed-wheel 79. movement ofthe rod 28 swings thev arm 2 1 The continued upward forward 011 the axle or pivot 16, and causes l the lifting lugs .41 to lift the h'ammer'lever 11 and thereby the nail. driver 12., The; same lifting movement of the rod .28 acts through the horn 33 to lift the work-rest 68 i i and thereby actuate the "pick-off 65 to pick ofi the forward nail from-the nail passage or slot5 and carry it into'the nozzle passage 64 immediately beneath the nail driver 12.

Just as the nail reaches this position,rthe

rod 28 has raised the hammer 11' sufficiently to cause the lifting lugs 41 to be wedged out of engagement with saidlever by the came 46 whereupon the heavy spring 48 instantly depresses the hammer 11 which, by its engagement with the collar 52, drives the driver 12 down with a hammer-like blowthereby driving and clenching the nail on. the cup-ended horn. As the operator releases the treadle, the springs 40 lower the work-supporter horn 33and as the workrest 68 correspondingly lowers, thespring 98 rotates the feed-wheel and positively feeds the work along on the horn the distance to which the feeding mechanism has been set. This nail driving operation and work vfeeding movement succeed each other in rapid repetition according to the speed with which the operator actuates the treadle. If at any time another kind or size of nail. is desired, the operator simply turns the handle 60 so as to bringthenozzle into line with the proper pocket or division ofthe hoppercontaining said nailsso that the lat ter may be selected for the next drive. For example, in driving nailsintoa heel, it is frequently desirable to have a row of heaviernails on oneside of the heel than on the other, and this selection may be accomplished at any moment without stoppingthe regular; driving operation of the machine. If a nall should get misplaced or if for any other reason it is desired to inspect the nozzle or feeding mechanism, it may quickly be done by simply pressing back the thumb piece 57 of the spring 56 and pulling off from the driver the nozzle and the mechanism carried by said nozzle. The nails are kept fed down continually to the lower end of the hopper by the operation of the latter. And for this purpose, I have provided the two slender rod supports 20, 21, which, bemg spaced apart as indicated in Fig. 2, and

tions without using the entire organism, as

is further pointed out in the claims.
